Kochi City: Castle, Hirome Market & Katsurahama (2026)

Kochi is the warm, easygoing capital of old Tosa, the southern province that gave Japan its seared-bonito dish and one of the great figures of the country’s modern founding, Sakamoto Ryoma. It is an unhurried city built for eating and walking, and at its centre stands a castle with a distinction no other in Japan can match. This guide explains how to combine the castle, the food hall, the temples of Mt Godaisan and the Pacific beach of Katsurahama into two well-paced days, with the prices, hours and timing you need for 2026 — and an honest word on where to stay, because the high end here is the heritage inn, not a branded tower.

At a glance — Duration: 2 days. Cost band: mid (castle ¥420, museums ¥500–850, meals the main daily cost, approx., 2026). Best season: year-round; the city is mild and southern. Who it’s for: first-timers, food lovers, history travellers. Base: a riverside ryokan in Kochi City.

Kochi Castle: the only keep and palace that survive together

Kochi Castle rides a low hill at the very centre of the city, and it holds a claim that sounds like a technicality until you stand inside it and grasp what it means: it is the only castle in Japan to keep both its original Edo-period wooden keep and its original honmaru palace — the lord’s residence — still standing together. Most of Japan’s twelve surviving original keeps have lost their palaces to fire, war or demolition; here both came through, so you can walk from the tatami audience rooms of the Kaitokukan palace straight up into the tower they were built to serve.

The castle was begun in 1601 by Yamauchi Kazutoyo after he was granted Tosa, rebuilt after a fire in 1749, and has survived every century since. You climb through the stone gates, pass through the palace, and ascend the steep internal stairs of the keep to a top floor that opens to a full circle of view over the city to the mountains and the sea. Entry to the keep and palace together is about ¥420 (approx., 2026), open roughly 9:00 to 17:00 with last entry at 16:30, closed only over the New Year. Allow ninety minutes, and go early when the light is good and the tour groups are still on the road.

The Sunday market and Hirome Market

Just east of the castle gate runs Otesuji, and on Sunday mornings it becomes one of the great street markets of Japan, held every week for some three hundred years. For about a kilometre, several hundred stalls sell the produce of Tosa — mountain vegetables and citrus, dried fish and yuzu, knives, tools and potted plants, country pickles and sweets — run by the growers themselves, so the prices are honest and the talk is direct. The local snack to eat in the hand is imoten, warm sweet-potato fritters. The market runs Sundays only, roughly 5:00 to 15:00 (shorter in winter), and it is closed on January 1–2 and during the Yosakoi festival week in August, so it is a wonderful piece of luck if your trip lands on a Sunday and simply not there if it does not.

Either way, the daily heart of how Kochi eats is Hirome Market, a covered hall of some sixty small stalls and shared tables a few steps from the castle, loud and crowded and the best lunch in the city. The dish to order is katsuo no tataki: bonito seared hard over a roaring straw fire until the skin is charred and smoky while the centre stays raw, then sliced thick and eaten with salt or ponzu, raw garlic and myoga. At the Myojinmaru stall they grill it in front of you over flaming rice straw; you carry the plate to a shared table with a glass of local sake. The hall runs roughly 10:00 to 22:00 (from 9:00 on Sundays), and a generous meal runs about ¥1,200–2,500 (approx., 2026). Our first-time Kochi City itinerary builds the castle, the market and Mt Godaisan into one relaxed first day.

Mt Godaisan: temple and botanical garden

Across the river east of the centre, the wooded hill of Mt Godaisan carries two of the city’s loveliest things side by side. Chikurinji is the thirty-first temple of the Shikoku eighty-eight-temple pilgrimage and the only one dedicated to Monju, the bodhisattva of wisdom; founded in the eighth century, it keeps a graceful five-storey pagoda among the cedars, a main hall that is a Nationally Important Cultural Property, and a celebrated Muromachi-period pond garden attributed to the priest-designer Muso Soseki. The garden and treasure house cost about ¥500 (approx., 2026), the grounds are free, and white-clad pilgrims still climb the stone steps.

Next door, the Makino Botanical Garden spreads over the hillside, founded in 1958 to honour Makino Tomitaro, the Kochi-born father of Japanese botany whose life inspired a 2023 national morning drama. Some 3,000 species grow across the slope in glasshouses and open beds, with curving timber pavilions framing the view to the city and the sea, and seasonal beds of camellia, iris and autumn grasses. Admission is about ¥850 (approx., 2026), open roughly 9:00 to 17:00. The two together make a calm, green afternoon above the city, about twenty minutes from the centre by car or bus.

Katsurahama and Sakamoto Ryoma

On the second day, head out to the Pacific at Katsurahama, the wide crescent of pale sand and pine-clad headland that is the most famous view in Kochi, woven into the old moon-viewing songs of Tosa. At its northern point stands the great bronze of Sakamoto Ryoma, over five metres tall on a high plinth, gazing out to the ocean toward the wider world he wanted Japan to join. The surf rolls in hard; the beach is for walking and looking, not swimming, as the currents are dangerous. It is free and always open, about thirty minutes by bus or car from the centre.

On the cliff above stands the Sakamoto Ryoma Memorial Museum, given over to the most beloved figure in Tosa. Born in Kochi in 1836, Ryoma left his domain to broker the alliance that toppled the shogunate and drafted an eight-point plan for a new national government before he was assassinated in Kyoto in 1867, aged thirty-one. The museum keeps his letters — vivid, funny, startlingly modern in voice — alongside the blood-stained screen from the scene of his death, and the rooftop terrace looks straight out over the Pacific he dreamed of crossing. Admission is about ¥500 (approx., 2026; more for special exhibitions), open year-round. It gives the bronze on the beach below its full meaning, and it is the emotional centre of any visit to Kochi.

Eating in Kochi

Kochi eats generously and locally. Beyond the straw-grilled bonito, the great set piece is sawachi-ryori, a vast platter that piles sashimi, sushi, fried and simmered dishes onto a single dish for sharing — the food of Tosa celebration, designed so that everyone reaches in and the sake keeps flowing. The province is proud of its sake, brewed dry to match the rich fish; the small reef fish and shellfish of the coast are excellent; and yuzu, the fragrant citrus Kochi grows more of than anywhere in Japan, turns up in everything from ponzu to sweets. For a last proper meal, a sit-down Tosa restaurant such as Tsukasa near Harimaya-bashi serves the classics in their full form, slower and quieter than the roar of Hirome.

Where to stay

Kochi has no international five-star hotel, so set expectations toward the heritage inn, which is genuinely the high end here. The Joseikan, founded in 1874 and standing on the bank of the Kagami River near the castle, is the most prestigious — a traditional ryokan with a rooftop bath looking over the river, Tosa kaiseki dinners built on the bay’s fish, and the kind of careful service that is the real luxury of the province. Business and city hotels cluster around the castle and the station for simpler stays; note that the large hotel long known as the New Hankyu has been changing names and brands through 2026, so confirm exactly what you are booking. Staying central puts the castle, Hirome and the tram lines all within easy reach.

Getting there and around

Kochi is reached by air from Tokyo and Osaka to Kochi Ryoma Airport, by limited express train across the mountains from Okayama, or by highway bus. In the city, the old trams of the Tosaden line run between the station, the castle and the suburbs, and a day pass is the simplest way around the centre; Katsurahama and Mt Godaisan are reached by local bus or car. You do not strictly need a car for this two-day route, though one makes the beach and the hill easier and is essential if you go on to the rivers or the capes elsewhere in Kochi.

FAQ

What makes Kochi Castle special among Japan’s original castles? It is the only castle in Japan to keep both its original Edo-period wooden keep and its original honmaru palace standing together. Japan has twelve surviving original keeps, but Kochi alone also kept the lord’s palace beside it, so you can walk from the audience rooms straight into the tower. Entry is about ¥420 (approx., 2026).

What is katsuo no tataki and where should I eat it? It is bonito seared hard over a straw fire so the outside is smoky and charred while the centre stays raw, sliced thick and eaten with salt or ponzu, garlic and myoga. The liveliest place to try it is Hirome Market beside the castle, where the Myojinmaru stall grills it in front of you over flaming straw.

Is the Kochi Sunday Market on every day? No — it is held on Sundays only, roughly 5:00 to 15:00, and is closed on January 1–2 and during the Yosakoi festival week in August. If your trip does not include a Sunday you will miss it, but Hirome Market gives you the same local food culture any day of the week.

Can I swim at Katsurahama? No. Katsurahama is a scenic beach with strong, dangerous currents, and it is for walking and looking rather than swimming. The draw is the sweep of sand and pine, the bronze statue of Sakamoto Ryoma at the northern point, and the museum on the cliff above.

How many days do I need in Kochi City? Two days is comfortable for the castle, Hirome Market, Mt Godaisan, Katsurahama and the Ryoma museum, with a night at a riverside ryokan in between. A single day can cover the castle and the food hall if you are short on time, but the city rewards an unhurried pace.
